If you have a TI-83 Plus calculator . You can go to 2nd X^-1 and use the matrices
Either B or C.
Im thinking more C.....
The two ys must be the same. Equate the two right hand sides.
-x + 10 = x + 2 add x to both sides.
10 = x + x + 2
10 = 2x + 2 Subtract 2 from both sides.
8 = 2x Divide by 2
x = 8/2
x = 4
Now solve for y
y = x + 2
y = 4 + 2
y = 6
Use the other equation to check it.
y = - x + 10
y = -4 + 10
y = 6
-69 is the answer i think
Answer:
676,000 possible license plate
Step-by-step explanation:
Each letter has 26 possible values (from A to Z), and each digit has 10 possible values (from 0 to 9).
So to find the number of license plates we can have, we just need to multiply the number of possible values for each letter and each digit, We have 2 letters and 3 digits, so we have:
Number of plates = 26 * 26 * 10 * 10 * 10 = 676000
We have 676,000 possible licence plates in this state.
